Solution
Q 4)
Answer: D. A and C
reagents A and C are correct to synthesize the given carboxylic acid compound
Q 5)
(CH 3 ) 3 C-Br + Mg/ether -----> (CH 3 ) 3 C-MgBr + CO2/H3O+ ------->Â Â (CH 3 ) 3 C-
COOH
(CH 3 ) 3 C-COOH + LiAlH4/H2O -------> (CH 3 ) 3 C-CH 2 OH
In last step carboxylic acid reduced to it corresponding alcohol product
