Question

The correct decreasing order for acid strength is :

• A. $NO_2CH_2COOH > NCCH_2COOH > FCH_2COOH > CICH_2COOH$
• B. $FCH_2COOH > NCCH_2COOH > NO_2CHCOOH > CICH_2COOH$
• C. $NO_2CH_2COOH > FCH_2COOH > CNCH_2COOH > CICH_2COOH$
• D. $CNCH_2COOH > O_2NCH_2COOH > FCH_2COOH > CICH_2COOH$

Answer 1

Answer: (A)

$NO_2CH_2COOH > NCCH_2COOH > FCH_2COOH > CICH_2COOH$

Answer 2

EWG increasea acidic strength $NO_2CH_2COOH > NCCH_2COOH > FCH_2COOH > CICH_2COOH$
