Fill your answer as the number of hydrogen atoms in Q.
Answer
9
Explanation
Solution
The reaction sequence involves the Wolff-Kishner reduction of acetophenone to ethylbenzene (P), followed by benzylic bromination of ethylbenzene with NBS to form 1-bromo-1-phenylethane (Q). The structure of Q is C₆H₅CHBrCH₃. The phenyl group (C₆H₅) has 5 hydrogen atoms. The -CHBr- group has 1 hydrogen atom. The -CH₃ group has 3 hydrogen atoms. Therefore, the total number of hydrogen atoms in Q is 5 + 1 + 3 = 9.
