An alkane $$C_{7}H_{16}$$ is produced by the reaction of lithium di(3-pentyl)cuprate with ethyl bromide. The name of the product is:

Product A is :

$$[P]\overset{Br_2}{\longrightarrow}C_2H_4Br_2\overset{NaNH_2}{\underset{NH_3}{\longrightarrow}}Q$$

Addition of HCl to alkene proceeds in two steps. the first step is the attack of $${H}^{+}$$ ion to $$_{\diagup}^{\diagdown}{C}={C}_{\diagdown}^{\diagup}$$ portion which can be shown as:

In the given reactions:
(i) $$CH_3Br \xrightarrow [  ]{ Na,ether } X \xrightarrow [ hv  ]{ Br_2 } Y \xrightarrow [  ]{ Na,ether } Z$$
(ii) $$CH_3COOH \xrightarrow [  ]{ NaOH } X \xrightarrow [ CaO ]{ NaOH } Y \xrightarrow [ hv  ]{ Br_2 } Z$$
Identify $$X,\, Y$$ and $$Z$$.

In the above reaction rate is fastest, when (X) is:
