Difference between molecular shape & shape

For example, for problem 4.13 it states to give the molecular shape whereas 4.15 states to give the shape, is there a difference between the two? Would molecular shape exclude lone pairs and shape doesn't?

I think they are the same. We always consider lone pairs when determining the shape of a molecule, even if we kind of ignore them when naming the shape. So an angular molecule is never trigonal planar whether we are talking about "shape" or "molecular shape".

Yeah, I think the terms are interchangeable as both point to the shape of the molecule, so both molecular shape and shape do not exclude lone pairs
