  1. work out the I2 molar mass ---> use periodic table (review how to calculate molar mass) -----> molar mass means mass of one mole ----> one mole means 6.022*10^23 molecules---->check how many atoms are there in one molecule and then how may are there in one mole -----> divide the molar mass with total number of atoms in one mole of I2---->this will give the mass of one atom of I
  2. Dehydration product is formed in both conditions on heating ...it is the elimination of alpha H by base (basic condition)or protonation of OH by acid (in acidic condition)
  3. According to IUPAC rule if there is tie for numbering as it appears in your example then we need to give lowest number alphabetically menas here in your example ethyl comes first so give 4 number to ethyl and 6 to methyl so the name is 2,6-dimethyl-4-ethyl.....
  4. You have to make strong basic conditions to remove alpha H (acidic) from acetone and this will give you Chloroform .
