There will be a slight distortion because you are joining 2 hydrogens and a … bond angle of nh4+, Once formed, this coordinate bond is identical to that of a normal covalent bond and all N-H bonds in NH4(+) are in fact identical. First, from these bond angles and Coulson's Theorem (ref_1, ref_2) we can determine that the C-H sigma bonds are $\ce{sp^{2.2}}$ hybridized and the C-C sigma bond is $\ce{sp^{1.7}}$ hybridized. These structures are very similar to a 'peace' sign, there is a central atom with three atoms around it, all on one plane. 2Cl s are each singly bonded to one carbon atom. The H-C-H bond angle is 117.6 while the H-C-C angle is 121. Thus, bond pair shifts towards Cl- atom and The triple bond between the 2 C- atoms has 1 sigma bond and 2 Pie bonds. 1 answer.
