Statement I: 2-bromobutane with (CH3)3COK in tertiary butanol gives 1-butene as the major product.

Statement II: Very strong base (CH3)3COK in tertiary butanol brings about E-2 elimination reaction.

Explanation:

E-2 elimination reaction is a type of elimination reaction in which a base removes a proton from the β-carbon of a leaving group, resulting in the formation of a double bond.

When 2-bromobutane reacts with (CH3)3COK in tertiary butanol, the strong base (CH3)3COK abstracts a proton from the β-carbon of 2-bromobutane. This leads to the formation of a carbanion intermediate. The carbanion then undergoes elimination of the bromide ion to form a double bond, resulting in the formation of 1-butene.

Now let's analyze each statement separately:

Statement I: 2-bromobutane with (CH3)3COK in tertiary butanol gives 1-butene as the major product.

This statement is correct. When 2-bromobutane reacts with (CH3)3COK in tertiary butanol, the major product formed is 1-butene. This is because the strong base (CH3)3COK favors the E-2 elimination reaction, which results in the formation of a double bond.

Statement II: Very strong base (CH3)3COK in tertiary butanol brings about E-2 elimination reaction.

This statement is also correct. (CH3)3COK is a very strong base and is capable of abstracting a proton from the β-carbon of a leaving group. In this case, the leaving group is the bromide ion in 2-bromobutane. The strong base (CH3)3COK in tertiary butanol brings about the E-2 elimination reaction by removing the proton and forming a double bond.

Explanation of the relationship between the two statements:

Statement II is the correct explanation of Statement I. The very strong base (CH3)3COK in tertiary butanol brings about the E-2 elimination reaction, which results in the formation of 1-butene as the major product. Therefore, both Statement I and Statement II are correct, and Statement II is the correct explanation of Statement I.

In conclusion, both Statement I and Statement II are correct, and Statement II is the correct explanation of Statement I.
