Q. Compound ‘A’ reacts with alcoholic KOH to yield compound ‘B’ which on ozonolysis followed by reaction with $Zn/H_{2}O$ gives methanal and propanal. Compound ‘A’ is
A) 1-propanol
B) 1-butanol
C) 1-chlorobutane
D) 1-chloropentane
Explanation
(c)
1-chlorobutane gives butene-1 on reaction with alc. KOH (dehydrohalogenation) which on ozonolysis yields methanal and propanal. The reaction is as follows
