It is because.monochlorinauon of
ethane. gives only ethyl chloride whereas monochlorination of pentane
gives three isomeric chloro
derivatives.

What is a haloform reaction?
The oxidative cleavage
of Methyl ketones as well as acetaldehyde and 2° terminal alcohol into into a
carboxylate anion and a trihalomethane (haloform) by the reaction of one
of halogen in the presence of strong alkali like NaOH or KOH is known as Haloform
reaction.
The respective halogen
can be chlorine, bromine or iodine.The methyl group of a methyl ketone is converted
into an trihalomethane by multiple subsequent steps, that involve
formation of an intermediate enolate anion.

Chlorination of ethane to ethyl chloride is more practicable than chlorination of n-Pentane to 1-Chloropentanc. Why ?What is the chemical formula of substances which gives a positive iodoform test?
The ketones containing terminal -COCH3 group generally gives positives Iodoform test. For example butan-2-one, Pentan-2-one, Acetone etc.
It is Most common test for terminal methyl ketones but Iodoform also given by terminal 2° alcohols like Ethanol (CH3CH2OH), Propan-2-ol (CH3CH2(OH) CH3 ), Butan-2-ol, Pentan-2-ol etc
Aldehyde does not gives Iodoform test positive except CH3CHO.
Methylene active hydrogen containg ketones also gives positive Iodoform test for example pentane-2,4-dione , Chatechol, and resorcinol etc

What is Chloretone ?
The Chemical (IUPAC) name of Chloretone is 1,1,1-trichloropropane-2-ol which is formed by reaction of chloroform and acetone in the presence of strong alkali like KOH.
Chloretone is act as Hypnotic (Sleep inducing agent ).

What is Phosgene gas ?
Phosgene is a chlorine containing highly poisonous gas, which formed by oxidation of chloroform in the presence of oxygen and sunlight.
To prevent the formation of Phosgene from chloroform following measures are taken
(1) chloroform kept in brown the bottles.
(2) these bottles are filled with capacity to exclude any air.
(3) 0.6. To 1.0% ethyl added to removed Phosgene formed.
