Answer 1

Answer:

There is no difference between ethene and ethylene.

Explanation:

Ethylene and ethene are one and the same compound, there is no difference between the two compounds.

Ethylene is the common name of the compound while ethene is its IUPAC name.

This hydrocarbon, ethene/ethylene is found in the group of hydrocarbons known as alkenes. It is the simplest hydrocarbon in this group of hydrocarbons with the formula C₂H₄.

Alkenes have the general formula of CₙH₂ₙ. These compounds have a carbon - carbon double bond.

        If not, then how come the (c) option is logical?

The option (C) is not logical and is probably a mistake made while making the question.

The correct statement for option (C) would probably be:

(C) Dehydrogenation of ethane to ethylene

   or, Dehydrogenation of ethane to ethene.

Answer 2

Explanation:

Molecular mass of glycol C2H4(OH)2 =62

Number of moles of C2H4(OH)2 = mass of glycol / molar mass of glycol

= 222.6/62=3.59 moles

Molality of solution = number of moles of solute / mass of solvent in Kg  

Mass of solvent = 200g = 200/1000 Kg = 0.2 kg

Plug the values we get

Molality = 3.59/0.2

Molality = 17.95

Formula of molarity of solution = number of moles of solute / volume of solution in Kg

Formula of volume = mass / density

Volume = 422.6g/(1.072 g/ml)

Volume = 394.21 ml

Convert in liter   

Volume in liter = 394.21 ml /1000 liter =0.394 liter
