Which of the following will have minimum C-Cl bond length?
In Ph-Cl, due to resonance C-Cl bond has partial double bond character and have minimum bond length.
A hydrocarbon (R) has six membered ring in which there is no unsaturation. Two alkyl groups are atttached to the ring adjacent to each other. One group has 3 carbon atoms with branching at 1st carbon atom of chain and another has 4 carbon atoms. The larger alkyl group has main chain of three carbon atoms of which second carbon is substituted. Correct IUPAC name of compound (R) is
Which of the following statements is not correct?
The configuration in a compound is independent of its physical properties (optical activity)
Choose the correct statement
Both +I and –I effect decreases with distance.
O

The IUPAC name of CH3-CH=CH-C-OH is:-
The IUPAC name of CH2=CH-CH=CH2 is:
The IUPAC name of CH2|COOH-CH2-CH2|COOH IS:
The IUPAC name of HOOC-CH=CH-COOH is:
The IUPAC name for HOOC-CH=CH-COOH is but-2-ene-1,4-dioic acid. The longest carbon chain has 4 carbon atoms, with a double bond at the 2nd position, and carboxyl (-COOH) groups at the 1st and 4th positions, hence the name but-2-ene-1,4-dioic acid.
The IUPAC name of CH3-CH=CH-COOH is:
The IUPAC name of CH3 -CHOH- CH2- CO-CH3 is:
The key functional groups are the alcohol (-OH) at carbon 4 and the ketone (>C=O) at carbon 2. The longest carbon chain is 5, so the root name is 'pentan'. The '4-hydroxy' prefix indicates the alcohol group at carbon 4, and the '2-one' suffix indicates the ketone group at carbon 2.
