Comprehension Type
Direction (Q. Nos. 23-27) This section contains a paragraph, describing theory, experiments, data, etc.
Five questions related to the paragraph have been given. Each question has only one correct answer among the four given options (a), (b), (c) and (d).
Passage
A chemist isolated a compound A with molecular formula C7H13Br. A undergoes very fast SN1 reaction. Spectroscopic evidence indicated that compound A has the following structural characteristics : It contains five sp3-hybridised carbon atoms. Among those five sp3 carbon atoms, three are methyl groups, one CH2 group and one CH group.
It also contains two sp2-hybridised carbon atoms. Also there is only one hydrogen atom attached to sp2 carbons.
The compound contains a total of six aliylic hydrogen atoms.
The carbon atom that holds the Br has one H attached to it.
Working Space
When compound A reacts with boiling water, it undergoes a SN1 reaction and produces two principal products B and C. Both B and C are alcohols with their molecular formula C7H14O. Among the two alcohols, B has the —OH group attached to a sp3 carbon atom that has no H -atoms bonded to it.
Q. 
How many stereoisomers are possible for A?
  • a)
    2
  • b)
    3
  • c)
    4
  • d)
    None of these
Correct answer is option 'C'. Can you explain this answer?

Explanation:

Given Information:
- Compound A has the molecular formula C7H13Br.
- It contains five sp3-hybridised carbon atoms.
- It contains two sp2-hybridised carbon atoms.
- There are six allylic hydrogen atoms in the compound.
- The carbon atom holding the Br has one H attached to it.

Determination of Stereoisomers:
- When identifying stereoisomers, we must consider the different possible arrangements of atoms in space.
- Since compound A has five sp3-hybridised carbon atoms, it can exhibit geometric isomerism.
- Geometric isomerism occurs when different spatial arrangements are possible due to restricted rotation around a double bond or ring.
- With two sp2-hybridised carbon atoms in compound A, it can also possess cis-trans isomerism if a double bond is present.

Calculating Possibilities:
- For geometric isomerism, we consider the three methyl groups and the two sp2-hybridised carbon atoms.
- The three methyl groups can have different spatial arrangements, leading to 2 stereoisomers.
- The two sp2-hybridised carbon atoms can also contribute to cis-trans isomerism if a double bond is present.
- Therefore, there can be a total of 2 geometric isomers and 2 cis-trans isomers, resulting in a total of 4 stereoisomers for compound A.

Final Answer:
- Hence, there are 4 possible stereoisomers for compound A.
