Answer 1

Hey buddy here is ur answers

[ANSWER 1]

A homologous series is aseries of organiccompounds having similar chemicalproperties due to the presence of same functional group. The members of ahomologous series are arranged in order of their increasing molar masses.Two consecutive members of ahomologous series differ by a –CH2– unit and a mass of 14 amu.

[ ANSWER 2 ]

The rkn u can see in pic ...I don't have much info about this answer sry...

[ ANSWER 3 ]

(i)Litmus test – Alcohol will have no effect on the litmus paper. Carboxylic acid acid will change blue litmus paper into red.

(ii)Reaction with sodium hydrogen carbonate – Alcohol has no reaction with sodium hydrogen carbonate (NaHCO3) but in the case of Carboxylic acid it reacts with NaHCO3 which gives CH3COONa, CO2 and H2O. The reaction is evident as the carbon dioxide will turn the lime water milky.

hope answer will be helpful to u .........
