Organic chemistry [Reasoning]

Pka value of carboxylic acid is decreases on increases electronegative group with carboxylic acid.
Haloarenes are much less reactive than haloalkanes towards Nucleophilic substitution reaction.
Why  1> 2> 3o  faster in Sn2? And  3> 2> 1o   faster in Sn1?
Pkb for aniline is more than that for methylamine
Methylamine react with ferric chloride to give precitate of ferric hydroxide.
Aniline does not undergo friedal craft reaction
Aldehydes are more reactive than ketones towards nucleophiles
Boiling point of aldehydes and ketones are lower than of the corresponding acids as well as alcohols
Aldehydes and ketones undergo a no. addition reaction
Ethanoic acid is weaker acid than benzoic acid
Basic strength  arrangement of amines[m. imp]
Why phenol do not give protation reaction readily
Boiling point of ethanol is higher than methoxymethane
Phenol is more acidic than alcohol [ethanol]
O-P – nitrophenol are more acidic than phenol
Why primary amines have higher boiling than tertiary amines.amines
Dipole moment of chlorobenzene is lower than that of cyclohexyl chloride
Alkyl halides though polar but immisible with water
What is racemic mixture
Chloromethane reacts with KCN to form ethane nitrile as main product but with AgCN to form methyl isocynide
Benzyl halides show high reactivity towards Sn1.
Benzoic acid does not undergo friedal craft reaction.
Gabriel phathalimide reaction give  only primary amines and it also do not give aniline?
Why Aniline give nitration on substantial amount on  m –position?
 Why aniline do not give direct nitration?
What is the limitations of Williamsons synthesis reagent?
What happens when excess of HI is reacted with ether
Why 2,2,5 trimethylcyclohexanone do not give cynohydrin very easily?
Why during formation of ester water shoid be removed imiediately?
Why carboxylic acid is acidic than phenol?
