Resonance for the methyl group at room temperature
The resonance for the methyl group at room temperature is a singlet. When the temperature is lowered, the resonance of this methyl group should have of two singlets, one for the conformation of 1-chloro-1-methylcyclo-hexane in which the methyl group is axial, and one for the conformation in which the methyl group is equatorial. The relative integrals of the two singlets will be proportional to the relative amounts of the two conformations. Because chlorine and methyl are about the similar size, there should be about equal amounts of the two conformations.
Element is strongly electropositive and Y is strongly electronegative. Both element are univalent, the compounds formed from their combination will be: (1) X + Y -

Q. A sample of water on analysis was found to contain the following analytical data: Mg (HCO 3 ) 3 = 16.8mg/L, MgCl 2 = 19mg/L, Mg (NO 3 ) 2 = 29.6 ppm, CaCO 3 = 20 p
Most polar solvents have Lewis base or donor properties resulting from lone-pair electrons. Good donor solvents inbuilt water, pyridine and ammonia, and are efficient at solvating
