Expert Solution

Which of the following statements is not correct about cholesterol?

a. it is an essential component of cell membranes --> TRUE, helps in cell structure

b. it is the precursor of steroid hormones --> TRUE, it is used in plenty of hormones

c. it is soluble in non-polar solvents --> TRUE, since it is nonpolar as well

d. it is soluble in polar solvents --> FALSE, it is nonpolar, thereofre, will not mix in water or any other polar species

Which intermolecular force exists between all molecules regardless of polarity?

London dispersion forces, which are created due to poles/electron displacement, there are slightly dipolo formation (Van der Waal Forces)

Which of the following compounds exhibits primarily dipole-dipole intermolecular forces?

a. CH3-O-CH3 --< nonpolar,

b. CH3CH3 --> nonpolar chain

c. CO2 --> forms two poles which cancel each other

d. F2 --> forms no dipole...

There is none present

dipole dipole can be formed slightly in ether, but will be very weak
