Structure of acetic vs formic acid

[Hannah Jin 1J]

Could someone help clarify why, structurally, CH3COOH (acetic acid) is a weaker acid than HCOOH (formic acid)? Thank you!

CH3COOH would be a weaker acid compared to HCOOH because you would consider the atoms bonded to the carboxyl group. If the atom attached to the carboxyl group tends to draw electrons, then the acid is strong. Although CH3COOH and HCOOH are both weak acids, the H atom in HCOOH tends to have more electron withdrawing power than CH3 in CH3COOH, which would make HCOOH (formic acid) the stronger acid.
