Question 1

Molecular Shape

Answer 1

There are ___ regions of electron density around the central ___ atom (___ single/double/triple bonds and ___ non-bonded pairs) which repel each other as far as possible to the ___° angles of a ___ shape. There is/are ___ non-bonding electron pair(s) on the central ___ atom, so therefore ___ corner(s) of this shape is/are not visible and a ___ shape is observed.

Question 2

Polarity

Answer 2

The molecule contains polar bonds due to the difference in electronegativity between ___ and ___. The symmetry of the ___ shape of the molecule causes the ___bond dipoles to cancel/not cancel each other out, so therefore the molecule is polar/non-polar.
