Ozonolysis of $2$-methylbut-$2$-ene yields

Alkenes convert into alcohols by:

In the reaction $CH_2=CH_2$ $\xrightarrow{HOCl} M$ $\xrightarrow{R} HO-CH_2-CH_2-OH$,where $M$ is a molecule and $R$ is a reagent,$M$ and $R$ are:

Alkenes react with water in the presence of acid to form alcohols. Identify the steps involved in the mechanism of the reaction from the following :
a) Nucleophilic addition of hydroxide ion to alkene
b) Protonation of alkene by electrophilic attack of $H_3O^{+}$
c) Electrophilic attack of $H_2O$ on carbanion
d) Nucleophilic attack of $H_2O$ on carbocation
e) Loss of $^{\ominus}OH$ to form an alcohol
f) Loss of $H^{\oplus}$ to form an alcohol

Which process converts olefins into paraffins?

The number of grams of bromine that will completely react with $5.0 \ g$ of pent$-1-$ene is $...... \times 10^{-2} \ g$. (Atomic mass of $Br = 80 \ g/mol$) [Nearest Integer]
