Question

Arrange the following is expected to have high density CH3F, CH3Cl , CH3Br, CH3I

Answer 1

Answer:

• Density: mass/volume
• To compare anything by diff things see uncommon
• Here mass of elements involves is c(CH3) ,uncommon is X( halogen)
• To compare property bt element
• same group ,Deciding factor(DF)= size/atomic radius( Fact :get to know in equilibrium)
• same period, DF= electonegativity
• Here, Size, Check relation bt comparative feature and size .
• Mass directly proportional size.
• Size increase down group
• Density in :I>Br>Cl>F, respective order.
