I need to know this

it says that the bond angle is reduced by 2.5 degrees for each lone pair.

so does that mean 1 lone electron reduces the bond angle by 2.5 degrees

or does it mean that a lone pair reduces the bond angle by 2.5 degrees (as in, you need two electrons that are not bonded to reduce the bond angle by 2.5 degrees)

'for each lone PAIR' , so yes, there must be two

i just want to make sure im getting this correct.

so there must be 2 electrons that are not bonded to reduce the bond angle.

also, how did you know this? school?

Two electrons=1 bond
A lone pair is equivalent to a bond(in terms of deciding the shape of the molecule) but it distorts it 2.5 degrees for EACH lone pair due to the region being more negatively charged and causing greater repulsion.

I took chemistry as an A Level(OCR exam board)

Every lone pair (bond) will reduce the angle by 2.5.

I'm also currently taking A level chemistry but for CIE (Cambridge international Examinations)
