Question

Which one of the following is most soluble in hexane (C_6H_14)? CH3CH2CH2CH2CH20H CH30H CH3CH2CH20H CH3CH2CH2CH20H CH3CH20H Ether layer is used to separate fibres inorganic impurities organic impurities none Distribution coefficient is represented by K S H G In fractionating column of fractional distillation, higher in column temperature becomes lower temperature becomes higher minimum absorption is carried out risks of sublimation exists Distillate formed after distillation is a diluted solution may contain impurities a condensed solution a concentrated solution A constant boiling mixture of two or more solution components is an ideal solution a noni deal solution an azeotrope all of the above

Explanation / Answer

30) Ans: A

A has more alkane componenet, so it iwill be more soluble in hexane.

31) Ans: C

Ether will separate the Organic layer.

32) Ans A

K is used for denoting Distribution coefficient

33) Ans : A

higher in column, the temperature become lower.

34) Ans : B

may contain impurities

35) Ans : C

Azeotrope
