The correct statement(s) regarding 1,2-butadiene(l) and 1,3-butadiene,...
The correct answers are options A & C
Adjacent hybrid orbitals are perpendicular to each other irrespective of the type of the hybridization. In 1,2-butadiene, adjacent 2× bonds are perpendicular to each other while in 1,3-butadiene, 2× bond and
1× bonds are adjacent to each other and the compound is a straight chain, so, the single bone and a double bond are perpendicular to each other and this is true for both the pairs of single and double bonds. Thus , both the pi orbitals in 1,3-butadiene are parallel to each other.

The correct statement(s) regarding 1,2-butadiene(l) and 1,3-butadiene,...
Explanation:
Statement I: 1,2-butadiene(l) has perpendicular pi planes.
Statement II: 1,3-butadiene has parallel pi planes.
Statement A: I has perpendicular pi planes while II has parallel pi planes
This statement is correct. In 1,2-butadiene(l), the two double bonds are present in a perpendicular arrangement with respect to each other. This is due to the presence of a sigma bond between the two carbon atoms in the middle. On the other hand, in 1,3-butadiene, the double bonds are present in a parallel arrangement with respect to each other.
Statement B: Both give the same product on adding 1.0 equivalent of HBr at -80°C
This statement is incorrect. When 1,2-butadiene(l) reacts with 1.0 equivalent of HBr at -80°C, it gives 2,2-dibromobutane as the product. On the other hand, when 1,3-butadiene reacts with 1.0 equivalent of HBr at -80°C, it gives 2,3-dibromobutane as the product. Therefore, the products obtained are different for the two compounds.
Statement C: I gives 2,2-dibromobutane while II gives 2,3-dibromobutane, when reacted with excess of HBr at very low temperature
This statement is correct. When 1,2-butadiene(l) reacts with excess HBr at very low temperature, it gives 2,2-dibromobutane as the major product. On the other hand, when 1,3-butadiene reacts with excess HBr at very low temperature, it gives 2,3-dibromobutane as the major product. This is due to the difference in the arrangement of the double bonds in the two compounds.
Statement D: Both have the same length of C=C double bonds
This statement is incorrect. The C=C double bonds in 1,2-butadiene(l) are shorter than the C=C double bonds in 1,3-butadiene. This is because in 1,2-butadiene(l), the double bonds are conjugated, which leads to increased bond strength and shorter bond length. On the other hand, in 1,3-butadiene, the double bonds are not conjugated, resulting in longer bond length.
Therefore, the correct statements are A) I has perpendicular pi planes while II has parallel pi planes and C) I gives 2,2-dibromobutane while II gives 2,3-dibromobutane when reacted with excess of HBr at very low temperature.
Statement I: 1,2-butadiene(l) has perpendicular pi planes.
Statement II: 1,3-butadiene has parallel pi planes.
Statement A: I has perpendicular pi planes while II has parallel pi planes
This statement is correct. In 1,2-butadiene(l), the two double bonds are present in a perpendicular arrangement with respect to each other. This is due to the presence of a sigma bond between the two carbon atoms in the middle. On the other hand, in 1,3-butadiene, the double bonds are present in a parallel arrangement with respect to each other.
Statement B: Both give the same product on adding 1.0 equivalent of HBr at -80°C
This statement is incorrect. When 1,2-butadiene(l) reacts with 1.0 equivalent of HBr at -80°C, it gives 2,2-dibromobutane as the product. On the other hand, when 1,3-butadiene reacts with 1.0 equivalent of HBr at -80°C, it gives 2,3-dibromobutane as the product. Therefore, the products obtained are different for the two compounds.
Statement C: I gives 2,2-dibromobutane while II gives 2,3-dibromobutane, when reacted with excess of HBr at very low temperature
This statement is correct. When 1,2-butadiene(l) reacts with excess HBr at very low temperature, it gives 2,2-dibromobutane as the major product. On the other hand, when 1,3-butadiene reacts with excess HBr at very low temperature, it gives 2,3-dibromobutane as the major product. This is due to the difference in the arrangement of the double bonds in the two compounds.
Statement D: Both have the same length of C=C double bonds
This statement is incorrect. The C=C double bonds in 1,2-butadiene(l) are shorter than the C=C double bonds in 1,3-butadiene. This is because in 1,2-butadiene(l), the double bonds are conjugated, which leads to increased bond strength and shorter bond length. On the other hand, in 1,3-butadiene, the double bonds are not conjugated, resulting in longer bond length.
Therefore, the correct statements are A) I has perpendicular pi planes while II has parallel pi planes and C) I gives 2,2-dibromobutane while II gives 2,3-dibromobutane when reacted with excess of HBr at very low temperature.
