Predict the molecular geometry and bond angle of ClNO.
Answer:
first, you have to know how many shared pairs there are.
shared pairs=1/2 (electrions required - valence electrons)
so SP=1/2(24-28)=3
so it’s either
Cl-N=O
or
Cl=N-O
(add the lone pair electrons so each atom has 8 electrons assigned to it)
to choose the best one you have to assign formal charges
Cl-N=O has a formal charge of +2
or
Cl=N-O has a formal charge of 0 so it is the better structure-- but you dont’ need that info.
Cl=N-O the N has to have 1 lone pair of electrons to complete it’s octet
the molecule is AX2E which is bent
(x2 = 2 Electron regions, E= one lone electron pair)
w/ angles ~120 degrees
