The formula of $D$ , a.k.a. $\text{diethyl ether}$ , is $(C_2H_5)_2O$ ; thus the total number of atoms in $D$ is $\boxed{15}$ .

Ethanol will NOT react with naoh as ethoxide is stronger base than naoh which will not remain on product side. The substitution you want to carry out would occur directly producing HBr as a by product

Yeah the substitution can directly occur . but in order to enhance the rat eof reaction we should add some strong base (capable enough to react with ethanol)

$NaOH$ has been replaced with $Na$ metal, which is capable of removing the hydrogens on alcohols. Thank you for bringing up the issue.

David Hontz - 4 years, 11 months ago

Yes right!. you should use stronger base like sodamide,Lithium di isopropyl amide etc

Prakhar Bindal - 4 years, 11 months ago

Thanks for bringing that up. I replaced $NaOH$ with $Na$ metal which is capable of stripping hydrogens from alcohols.

bhai na dalne se oh - kyo nahi nikla h+ kyo nikla ? ( i have read it that alcohols give sodium alkoxide on reaction with Na plz tell me why?)
