Which from following is a primary benzylic alcohol?
Options
- AC ₆ H ₅ CH ₂ OH
- BC ₆ H ₅ - CH ^ CH ₃ _ OH .
- CH ₂ C = CH - CH ^ CH ₃ _ OH .
- DH ₂ C = CH - CH ₂ OH
Correct answer
A. C ₆ H ₅ CH ₂ OH
Step-by-step solution
A benzylic alcohol contains an -OH group attached to an sp^3 hybridized carbon atom directly bonded to an aromatic ring. A primary alcohol has the -OH group attached to a primary carbon atom (a carbon bonded to only one other carbon). In C ₆ H ₅ CH ₂ OH , the -OH group is attached to a CH ₂ group which is directly bonded to the benzene ring. Thus, it is a primary benzylic alcohol. In C ₆ H ₅ CH ( OH ) CH ₃ , the -OH group is attached to a secondary carbon, making it a secondary benzylic alcohol. H ₂ C = CH - CH ( O
