Question

In a soap micelle, the soap molecules are arranged radially with :
(a) ionic ends directed towards the centre and hydrocarbon ends directed outwards
(b) hydrocarbon ends directed towards the centre and ionic ends directed outwards
(c) both ionic ends and hydrocarbon ends directed towards the centre
(d) both hydrocarbon ends and ionic ends directed outwards

Solution

(b) hydrocarbon ends directed towards the centre and ionic ends directed outwards.

In a soap micelle, the soap molecules are arranged radially with the hydrocarbon ends, i.e. hydrophobic, directed towards the centre; and, ionic ends, i.e. hydrophilic, directed outwards.

Q. Assertion :Two identical conical pipes, as shown in figure have a drop of water. The water drop tends to move towards tapered end.
