Definition of Hydrogen bonding
Check what you remember
Read the wording for your board, then hide it and explain Hydrogen bonding in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
The δ⁺ hydrogen of one water molecule is attracted to the δ⁻ oxygen of a neighbouring molecule, and each water molecule can bond with up to four others.
