1.	An organic compound A containing C = 70% and H =11.6% gave the following results : (P) 0.384 gm of the compound A displaced 100 ml of air at 1 atm and 273 K. (Q) On treatment with PCl_(3)A gave another compound, which contained 33.97%(34%)chlorine. IUPAC anme of the compound A is :
Answer» pentanal 2- pentanone cyclopentanol 1,3-epoxypentane Solution :For empirical formula `{:("Element",%,"At.Wt.","Ralative ratio","Simple ratio"),(C,70,12,5.83,5.06(5)),(H,11.6,1,11.6,10.086(10)),(O,18.4,16,1.15,1(0)):}` So, ORGANIC compound`(C_(5)H_(10)O)_(x)` MOLECULAR waight`=(WRT)/(PxxV)=(0.384xx0.0821xx273)/(1xx(100)/(1000))` `""=86` `""86xx = 86` `rArr""`x = 1 So, compounA is `C_(5)H_(10)O`. If compound A is alodohol. `C_(5)H_(10)Ooverset(PCl_(5))rarrC_(5)H_(9)Cl` `(12xx5+9+35.5=104.5)""(%Cl=(35.5)/(104.5)=33.97)`
