Explanation / Answer

Q1.

helix is inherently chiral --> it depends... if does not possess a stereogenic center

Q2

clearly a aminoglycosidic bond, since R-NH-R presence

Q3

ionic bond, due to the negative charge of phopshate

Q4.

R-helix

Q5.

as stated before, this is mirror image, so it must be LH helix

Q6.

this is an ester (C-O and C=O)

Q7.

this must be an amide, due to the NH2 and C=O bonds

Q8

this is an ester, since R-O-R is present
