I'm struggling with some tasks connected with chirality. I've done some examples but I'm not sure if I'm correct. Can you help me also with the rest? Thank you!
(a) chiral;
(b) achiral;

(e) achiral;
(f) chiral;
(g) achiral;
(h)

Please give us your thoughts on those about which you are unsure.

my thoughts:
(h) chiral
(i) also chiral?
(k) achiral
(l) chiral

Does j have a plane of symmetry? I agree about k, but what was your reason?

You have one wrong I think.

I think g is chiral - it is like a cumulene with 4 different substituents. Like XYC=C=CWZ

I think G is chiral as well.

k and l: Are there 4 different entities attached to the carbon in question? Now answer.

d and f are achiral because they have a centre of inversion.
