`underset("ethanal")(CH_(3)CHO+3N_(a)OI)overset(NaOH//I_(2))underset(Delta)rarrCHI_(3)+underset("(Yellow ppt.)")(HCOON_(a)+2N_(a)OH)`
(a) (i) `CH_(3)-underset(O)underset(||)C-CH_(3)overset(Zn-Hg)underset(Conc.HCl)rarrCH_(3)CH_(2)CH_(3)`
(ii) `CH_(3)-underset(O)underset(||)C-Cl+H_(2)overset(Pd-BasO_(4))underset("boiling xylene")rarrCH_(3)CHO+HCl`
(iii)
(i) `F-CH_(2) COOH` is stronger acid as higher (-I effect), stronger is the acid. Order of (-I) effect `=IltBrltClltF.`
(ii) acetic acid is stronger acid than phenol.
