IB Chemistry 2.2.2 Bond types and strength Questions
Sharpen bond-length and bond-strength answers by comparing real molecules, using bond order, and reading the limits IB accepts from data-booklet values.
How this is tested
- identify CO as the molecule with the shortest C-O bond when comparing CH3OH, H2CO, CO and CO2
- predict each S-O bond length as between 121 pm and 161 pm from the data booklet, with one value for all bonds
- compare bond strength and UV absorption in oxygen and ozone, and relate a shorter bond to stronger bonding
