in ammonia as N has mre e.n. than H,bond pair of electrons are more towards it which causes repulsion with lone pair of electrons,and they tend o move away but in nf3 bond pair of electrons are away from flourine so they can have lesser bond angle
Oxygen difluoride (OF2) has a larger bond angle than carbon dioxide (CO2). OF2 has a bond angle of around 103 degrees, while CO2 has a bond angle of 180 degrees due to its linear molecular geometry.
The bond angle in H2S (92 degrees) is less than in H2O (104.5 degrees) due to the larger size of sulfur compared to oxygen. The larger size of sulfur results in weaker repulsions between the electron pairs, causing the bond angle to be smaller in H2S compared to H2O.
Oxygen difluoride (OF2) has a larger bond angle than carbon dioxide (CO2). OF2 has a bond angle of 103.3 degrees while CO2 has a bond angle of 180 degrees. This is because OF2 has two lone pairs of electrons on the central oxygen atom, causing the fluorine atoms to be pushed closer together, resulting in a smaller bond angle.
The ammonia molecule has a observed bond orientation due to its trigonal pyramidal shape. This shape is a result of the lone pair of electrons on the nitrogen atom that repels the bonding electron pairs, causing the H-N-H bond angle to be less than 109.5 degrees.
Its more a matter of whether the bond has a smaller angle than bonds in other very similar compounds. A smaller angle than expected is said to cause strain- i.e. it breaks more easily. Examples from organic chemistry include cyclo alkanes with bond angles less than tetrahedral.

In CH2F2, the bond angle between the carbon-hydrogen bonds will be greater than the bond angle between the carbon-fluorine bonds. This is because hydrogen atoms have a smaller size compared to fluorine atoms, causing repulsion between the larger fluorine atoms to decrease the carbon-hydrogen bond angle.

An obtuse angle is larger than a acute angle
The bond angles in water and ammonia are less than the ideal value of 109.5 degrees because of lone pair-bond pair repulsions. The presence of lone pairs on the central atom causes greater electron-electron repulsions, pushing the bonding pairs closer together and decreasing the bond angle.
Draw an angle that is larger than a right angle label the vertex k
Ozone (O₃) has a bond angle of approximately 117 degrees, which is larger than water's bond angle of about 104.5 degrees. This difference is primarily due to the presence of resonance structures in ozone, which allows for a more spread-out electron distribution and reduces the repulsion between bonding pairs. In contrast, water has two lone pairs that exert greater repulsive forces on the bonding pairs, resulting in a smaller bond angle. Additionally, the molecular geometry of ozone is bent, but it experiences less steric hindrance compared to water.

ClO3 has the smaller bond angle than ClO4
