निम्नलिखित जलीय विलयनों पर विचार कीजिए।
I. 2.2 g ग्लूकोज 125 mL विलयन में।
II. 1.9 g कैल्सियम क्लोराइड 250 mL विलयन में।
III. 9.0 g यूरिया 500 mL विलयन में।
IV. 20.5 g ऐलुमिनियम सल्फेट 750 mL विलयन में।
इन विलयनों के क्वथनांक का सही बढ़ता क्रम होगा:
[दिया है: मोलर द्रव्यमान \(g mol^{-1}\) में: \(H=1, C=12, N=14, O=16, Cl=35.5, Ca=40, Al=27, S=32\)]

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
