The unbonded electron pairs repel the chloringe atoms.
The small size of the central nitrogen means the larger chloride atoms cannot approach close enough to form stable N-Cl bonds due to mutual repulsive forces becoming dominant. it is due to the absence of vacant dorbitals in N atom
ITS BENT thats why you always see molecular pictures of the molecule like this O / \ H H and not like this H-O-H It has to do with the numbers of lone pairs bonded to the central atom (O)
Carbon tetrachloride, or CCl4, is a molecule with four chloride atoms and a central carbon atom. It has a tetrahedral molecular shape. It is a clear liquid with a sweet odor and readily evaporates. In the past, carbon tetrachloride was used as a pesticide and cleaning agent. It was also used in fire extinguishers and in producing refrigerants and aerosols. Because carbon tetrachloride has been found to affect the ozone layer of the atmosphere, its usage is declining.
The NO2 molecule is a bent molecule with a central nitrogen attached to two oxygen atoms. The bond angle between the N-O bonds is 134.30
Cyanogen bromide is a molecule consisting of three atoms. There is a central carbon atom triple-bonded to a nitrogen on one side and single-bonded to a bromine on the other side. The C-N triple bond consists of one sigma bond and two pi bonds, while the C-Br single bond is one sigma bond. The angle between the two bonds is 180 degrees, making this a linear molecule. The central carbon is sp-hybridized.

Cyanogen chloride is a molecule consisting of three atoms. There is a central carbon atom, with a nitrogen triple-bonded on one side and a chlorine single-bonded on the other side. The angle between the two bonds is 180 degrees, making this a linear molecule. The C-N triple bond consists of a sigma bond and two pi bonds, while the C-Cl single bond consists of one sigma bond. The central carbon is sp-hybridized.
When the central atom of a molecule has unshared electron, the bond angles will be less than when all the central atom's electrons are shared.
GeF2 is a bent molecule with two single bonds and one lone pair on the central atom (Ge). The two fluorines have six electrons (dots) around them along with the single bond to germanium. The central atom's hybridization is SP2 and the AXE scheme is AX2E. The angle between the two fluorines is about 118o.
Consider: Number of bonding domains on the central atom Number of non-bonding electron pairs (lone pairs) on the central atom

France does have a large coast line on the west side. Also, partly on the South. Paris, the city, is not near a coast, but rather in the north central part of the country.
The linear shape of beryllium chloride is due to the fact that it has a small central atom relative to the size of the chlorine atoms. This results in a small bond angle and a linear shape. The angular shape of water molecule is due to the fact that it has a large central atom relative to the size of the hydrogen atoms. This results in a large bond angle and an angular shape.
IN an ammonia molecule the central nitrogen atom has 3 three bonds.
