Question

the first question
Q. A hydrocarbon Y decolorizes bromine water. On ozonolysis it gives 3-methyl butanal and formaldehyde. Give the name and formula of the compound with the respective ozonolysis reaction.
(ii) Write one reaction to show the acidic nature of ethyne.
(iii) State Markovnicoff's rule. Using this write the reaction of propene with HCl

Solution

$C H_{3} C H (C H_{3}) C H_{2} C H = C H_{2} + O_{3} \to C H_{3} C H (C H_{3}) C H_{2} C H O + H C H O 4 - m e t h y l p e n t - 1 - e n e 3 - m e t h y l b u t a n a l$
Hence, in the above reaction shows that Hydrocarbon Y is 4-methylpent-1-ene , (formula = CH₃CH(CH₃)CH₂CH=CH₂) which on ozonolysis (O₃) gives 3-methyl butanal ,CH₃CH(CH₃)CH₂CHO and formaldehyde, HCHO.
