Question

Identify A and B in the following reaction
`CH_(3)-CH_(3)overset(B)rarrCH_(3)COOHoverset(A)rarrCH_(3)CH_(2)OH`
A. `{:(A,B),("HI+redP",LIAlH_(4)):}`
B. `{:(A,B),(NI//Delta,LIAIH_(4)):}`
C. `{:(A,B),(LiAIH_(4),"HI+red P"):}`
D. `{:(A,B),(Pd-BaSO_(4),Zn+HCl):}`

Answer 1

Correct Answer - c
Acetic acid on reduction with lithium aluminiumhydride `(LiAlH_(4))` gives ethyl alcohol while on reduction with HI and red P gives ethane.
`CH_(3)COOHoverset(LiAlH_(4))Rarroverset("Ethyl alcohol")CH_(3)CH_(2)OH`
