What is the increasing order of reactivity of the following alkyl halides in the Williamson synthesis?
$I. \, CH_2 = CHCH_2Cl$
$II. \, CH_3CH_2CH_2Br$
$III. \, (CH_3)_3CCH_2Br$
$IV. \, CH_3CH_2CH_2Cl$

Which of the following statements are correct for phenol?
$(A)$ In general,phenol is more acidic than alcohol.
$(B)$ Phenol is used in the production of melamine plastic.
$(C)$ Phenol gives violet colour with neutral ferric chloride solution.
$(D)$ Phenol when heated with acetyl chloride gives phenetole.

Column $(I)$ contains products and Column $(II)$ contains the processes to prepare them. Match the processes in Column $(II)$ with the products in Column $(I)$.

Column - $(I)$ Product	Column - $(II)$ Preparation Process
$(A)$ Butan$-1-$ol	$(i)$ Hydration of propene in the presence of dilute sulfuric acid
$(B)$ Propan$-2-$ol	$(ii)$ Reaction of propanone with methylmagnesium bromide followed by hydrolysis
$(C)$ $2-$Methylpropan$-2-$ol	$(iii)$ Hydroboration of propene followed by reaction with $(NaOH + H_2O_2)$
$(D)$ Propan$-1-$ol	$(iv)$ Catalytic reduction of butanal

The correct match about the reaction sequence shown above is:

In which of the following reactions is phenol or sodium phenoxide $NOT$ formed?

From the following compounds,determine the number of compounds that give $(i)$ a red colouration with ceric ammonium nitrate and $(ii)$ a positive iodoform test: $...........$.
