RNA and DNA are chiral molecules, their chirality is due to:
L -sugar component
chiral bases
chiral phosphate ester units
chiral phosphate ester units
D.
chiral phosphate ester units
RNA and DNA molecules have ribose and deoxyribose sugar respectively. Both are chiral, their chirality is due to D -ribose or deoxyribose sugar components.

Consider the following compounds:
The correct decreasing order of their reactivity towards hydrolysis is;
(ii) >(iv) > (iii) > (i)
(i) > (ii) > (iii) > (iv)
(iv) > (ii) > (i) > (iii)
(iv) > (ii) > (i) > (iii)
The product formed in aldol condensation is:
a beta-hydroxy acid
a beta -hydroxy aldehyde or ketone
an alpha -hydroxy aldehyde or ketone
an alpha -hydroxy aldehyde or ketone
The order of decreasing reactivity towards an electrophilic reagent, for the following:
i) Benzene
ii) Toluene
iii) Chlorobenzene
iv) Phenol
would be:
(i) > (ii) > (iii) > (iv)
(ii) > (iv) > (i) > (iii)
(iv) > (iii) > (ii) >(i)
(iv) > (iii) > (ii) >(i)
