homework 6C. 21b

Postby Ashley R 1A » Fri Dec 06, 2019 2:13 pm

The question asks how you compare the bond strength of acetic acid CH3COOH to formic acid HCOOH. Why is formic acid a stronger acid? I was going based off of the size and thought that because acetic acid molecule is larger, it would more easily deprotonate.

The CH3 group has electron donating properties, making it less electron withdrawing than the H attached to the carboxyl group in formic acid. That’s why formic acid is slightly stronger than CH3COOH

what rule or reasoning does this fall under? did he cover electron-donating abilities in lecture?
