Question
In the reaction of CH3CH2CH=CH2 with HCl, the H of the HCl will become attached to which carbon?
Correct Answer
Option A is the correct answer.
Detailed Explanation
The molecule is 1-butene (CH3CH2CH=CH2). According to Markovnikov's rule, the H from HCl adds to C-1 (the terminal carbon) because it already has more hydrogens (two H atoms) compared to C-2 (one H atom).
Hint
Which carbon has more hydrogens in 1-butene?
