The bond angle in formic acid (HCOOH) is less than 116 degrees because of steric hindrance and repulsion between the lone pairs of electrons on the adjacent oxygen and carbon atoms. This causes the atoms to be closer together than if the lone pairs were further apart, resulting in a smaller bond angle.
The bond angle for H2S is approximately 92 degrees.
180 degrees and it is linear
The bond angle of AlCl3 is 120 degrees.
The bond angle of N2O is 180 degrees.
The bond angle for Cl2O is approximately 110 degrees.
The bond angle of hypochlorous acid (HOCl) is approximately 104.5 degrees.
The bond angle for H2S is approximately 92 degrees.
BH3 has a bond angle of 120 degrees.
The bond angle of BF2 is 120 degrees.
180 degrees and it is linear
The bond angle in CO2 is 180 degrees.
The bond angle of AlCl3 is 120 degrees.
The bond angle of N2O is 180 degrees.
The bond angle for Cl2O is approximately 110 degrees.
The bond angle of acetylene (C2H2) is 180 degrees.
Formic acid is more acidic because formic acid is a smaller molecule as compare to acetic acid so polarity is working in small area and O-H bond is more polar HCOOH, in acetic acid the additional CH3- group is an electrons donor group so O-H bond is little bit stronger and less polar so it is weaker acid.
The bond angle of IF5 is approximately 90 degrees.
