Definition of Bond polarity and lone pairs
Check what you remember
Read the wording for your board, then hide it and explain Bond polarity and lone pairs in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
The polar O–H bonds leave hydrogen partially positive and oxygen partially negative, so lone pairs attract neighbouring hydrogen atoms.
