Answer -
(i)┬аphenol┬а(ii)┬аtoluene┬а(iii)┬аformic acid
(iv)┬аethylene glycol┬а(v)┬аchloroform┬а(vi)┬аpentanol.
Answer
(i)┬аPhenol(C6H5OH) has the polar group тИТOH and non-polar group тИТC6H5.Thus, phenol is partially soluble in water.
(ii)┬аToluene(C6H5тИТCH3) has no polar groups. Thus, tolueneis insoluble in water.
(iii)┬аFormicacid (HCOOH) has the polar group тИТOH and can form H-bond with water. Thus,formic acid is highly soluble in water.
(iv)┬аEthyleneglycol┬а
┬аhas polar тИТOH group and canform HтИТbond. Thus, it is highly soluble in water.
(v)┬аChloroformis insoluble in water.
(vi)┬аPentanol(C5H11OH) has polar тИТOH group, but it also contains avery bulky non-polar ┬н┬н┬нтИТC5H11┬аgroup. Thus, pentanolis partially soluble in water.
