Question asks about Symmetry, Chirality of molecules.

C) cis-2-chlorocyclopropane
D) trans-2-chlorocyclopropane

Answer key states both molecules are chiral. I'm not sure how this is the case as both molecules fail the rule of 4-different substituents.
 - C2 bears Cl, H, 2x CH2
 - C1 & C2 both bear H2, CH2, CHCl

Also, how can a molecule with only one non-hydrogen substituent be cis/trans? I've built the molecule but seem to be blanking on the rationale that allows cis/trans

Thanks in advance guys

Seems to me that you're missing a descriptor of what's on carbon-1, at the very least, which would help both the cis/trans and the chirality question. What's the full question?

I thought so as well. There are an amazing amount of typos in this text.

That actually is the full question.
