<p>Do they ask about in-depth stuff, like the angles? 120, 180, etc? What do they ask? WHat do they ignore?</p>
<p>If anything, I think they only ask about bond angles .. know that bond angles in water is 109.5</p>
<p>I've never encountered a bond angle question. Just know hybridization (no of areas of electron density around center atom) and molecular geometry.</p>
