Which of the following compound does not contain sulphur atom?
Given below are two statements :
Statement I : Phenols are weakly acidic.
Statement II : Therefore they are freely soluble in NaOH solution and are weaker acids than alcohols and water.
Choose the most appropriate option :
Geraniol, a volatile organic compound, is a component of rose oil. The density of the vapour is 0.46 gL$$-$$1 at 257$$^\circ$$C and 100 mm Hg. The molar mass of geraniol is ____________ g mol$$-$$1. (Nearest Integer)
[Given : R = 0.082 L atm K$$-$$1 mol$$-$$1]
17.0 g of NH3 completely vapourises at $$-$$33.42$$^\circ$$C and 1 bar pressure and the enthalpy change in the process is 23.4 kJ mol$$-$$1. The enthalpy change for the vapourisation of 85 g of NH3 under the same conditions is _________ kJ.
