Arrange the following in the increasing order of the property mentioned: (a) CH_3 COOH, ClCH_2 COOH, FCH_2 COOH (Acid strength) (b) CH_3 CHO, CH_3…
Arrange the following in the increasing order of the property mentioned :
(a)
$\displaystyle \mathrm{CH}_{3} \mathrm{COOH}, \mathrm{ClCH}_{2} \mathrm{COOH}, \mathrm{FCH}_{2} \mathrm{COOH}$ (Acid strength)
(b)
$\displaystyle \mathrm{CH}_{3} \mathrm{CHO}, \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OH}, \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{3}$ (Boiling Points)
Marking-scheme solution
(a) \(\displaystyle \mathrm{CH}_{3} \mathrm{COOH}<\mathrm{ClCH}_{2} \mathrm{COOH}<\mathrm{FCH}_{2} \mathrm{COOH}\)
(b) \(\displaystyle \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{3}<\mathrm{CH}_{3} \mathrm{CHO}<\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OH}\)
