both A and B
none of these

Question 10 Multiple Choice (Single Answer)

alkoxy group
alkyl group
carbonyl group
epoxy group

Question 11 Multiple Choice (Single Answer)

In ethers the numbering of the parent chain is done in a way:

that the carbon atom linked to the -O-atom gets the lowest number.
that the carbon atom linked to the -O-atom gets the highest number.
that the carbon atom which comes from parental hydrocarbon linked to the -O-atom gets the lowest number
none of these

Question 12 Multiple Choice (Single Answer)

Which of the following statement is not correct in the naming of ethers according to IUPAC rules?

Ethers are named as alkoxy alkanes
The numbering of the parent chain is done in such a way so that the carbon atom linked to the -O-atom gets the lowest number.
The two alkyl groups attached to the oxygen are put in alphabetical order
In the case of simple ethers, the prefix tri is attached before the name of the alkyl group.

If a substituent is an alcohol, the alcohol has higher priority
If a substituent is a halide, ether has higher priority
If both an alcohol group and a halide are present, alcohol has higher priority
If a substituent is an alcohol, the ether has higher priority
