JEE Main 2014 · 11 Apr · Shift 1, Chemistry question 59
Answer and worked solution
Official answer: C
In phenol the C-O bond (about 136 pm) is shortened by resonance and carbon. In methanol it is about 142 pm, so methanol's C-O bond is longer, and statement (3) is not correct.
The other statements are correct as given: alcohols are weaker acids than water, acidity falls from primary to tertiary, and the C-O-H angle is 108.9°.
