Ilyas Abbas on Nearpeer MDCAT Common Room
Can any one guide ya mcq Kyu galat huwa ? Because in ethane their are only two carbons and chlorine jis k sath bi attach ho usay carbon number 1 kaha jaya ga ...so ..2 chloroethane is wrong one

IUPAC myn halide pehly aur phir alkali likhty hyn "HALOALKANES"...LAKIN C myn ulta hay jabky D bilkul thik hay . Sawal dekhyn unhon ny kaha keh jo IUPAC rules follow na kary so option C nahin kerta q keh woh tou common name hay .

Option 4 bi to ghalat ha ap uska structure draw kar ka dekhy

Word secondary or tertiary not used in IUPAC system

I know but option D is wrong too

CH₃–CH₂–Cl ,2-chloroethane ya phir just chloroethane kehna zyada behtar hoga ...q keh ethane ky saath halide laga hay ...aur option C IUPAC naming rules ky mutabiq zyada ghalat hay .

Bcz IUPAC rules do not involve pri,sec,and tert as they are adopted for common system.In IUPAC just select the long chain followed by branch name and position and that's it.
