Question

Hi class 10 friends help science 5 no 2 number what's this structure name☺️☺️☺️☺️❤️❤️❤️plz

Answer 1

ANSWER :

1. 1-Bromo Ethane.

Reason : Since Bromine is in the 1st carbon of the parent chain so 1-Bromo. Since the parent chain consists of two Carbons so it is written 'Eth' and due to single bonds it is written as 'ane'.

2. Methanone

Reason : The structure conatains the functional group called ketone so 'one' is used. Since the parent chain chain consists of 1 carbon only so 'Meth' is used.

3. Hex-1-yne or Hexyne

Reason : Number the parent chain from the carbon nearest to the triple bond. So we get the triple bond on the 1st carbon. Hence, it is wriiten as '1-yne' ; 'yne' due to triple bond (alkyne). There are Seven Carbons in the parent chain hence 'hex'.
