Unknown compound solubility (g/100 ml water) a 4 b 0.25 which of the following correctly explains the identity of compound a and its solubility? it is an amine; it contains a nitrogen atom that will allow nitrogen-hydrogen bonds to form while in water. it is an ether because the oxygen atom is within the carbon chain, so is free to form oxy-hydrogen bonds to make it more soluble is an etherthe polarity of the oxygen-hydrogen bond makes it more soluble. is an amine: because the lower electronegativity of n h makes it more soluble
