Conc. $H_2SO_4$ reacts with $C_2H_5OH$ at $170\,^{\circ}C$ to form

In the reaction with $HCl$,an alkene reacts in accordance with the Markovnikov's rule to give a product $1-$chloro$-1-$methylcyclohexane. The possible alkene is

The number of $sp^3$ hybridized carbon atoms in cyclohexene is

Which hydrogen halide adds to propene in the presence of peroxide following the anti-Markovnikov rule?

$\underset{C_7H_{14}}{(A)} \xrightarrow[Zn/AcOH]{O_3} (B) + (C)$
Compound $(A)$ exists as geometrical isomers and $(B)$ gives the Cannizzaro reaction. $(A)$ will be:

$CH_3-C(CH_3)=CH_2$ $\xrightarrow[R_2O_2]{HBr} X$ $\xrightarrow{CH_3ONa} Y$; $X$ and $Y$ are:
