Question

An alekene X is obtained by dehydration of ann alcohol Y. X on ozonolysis gives two molecules of ethanal for every molecule of alkene. X and Y are
A. X=3-hexene,Y=3-hexanol
B. X=2-butene, Y=2-butanol
C. X=1-butene, Y=1-butanol
D. X=1-hexane, Y=1-hexanol

Answer 1

Correct Answer - B
Products of ozonolysis:
`CH_(3)-overset(H)overset(|)(C)=O+O=overset(H)overset(|)(C)-CH_(3) to underset("2-Butene")(CH_(3)CH=CHCH_(3))`
2-butene is obtained by dehydration of 2-butanol.
`CH_(3)-CH_(2)-underset(OH)underset(|)(C)H-CH_(3)overset(H^(+))to CH_(3)-CH=CH-CH_(3)+H_(2)O`
