Will elevation in boiling point be same for 0.1 m NaCl and 0.1m sucrose solution?

No, if both substances are dissolved in water, because sodium chloride spontaneously dissociates into two ions that act independently in raising the boiling point, while dissolved sucrose does not dissociate into entities smaller than molecules. Therefore, 0.1 m NaCl will raise the boiling point about twice as much as 0.1 m sucrose.
