Answer 1

- 1 According to markonikoff's rule, the the past of Hel attacks the Carbon having more no of hydrogen - Here secondary Corso cahon is formed @kalced gcarlo Cahon. a is the answer

Given alkene is 4-methyl 1,3 butadiene.

When HCl is added to the Alkene, +ve part of the Alkene adds to the carbon having more number of Hydrogens.

As carbon-1 has 2 Hydrogens, according to Markonikoff rule, Hydronium ion attacks the carbon having more number of Hydrogens.
