Question

Indicate True (T) or False (F) for each of the followingstatements, Explain why if it is FALSE
(a) Salicylic acid is an equilibrium mixture of twoconstitutional isomers. (b) Electronegativity is a measure of the ability of anelement to attract shared electrons in a covalent bond. (c) All carbon-carbon bonds in benzene have bond lengths inbetween that of a single bond and a double bond. (d) A dipole moment is a vector; it has both magnitude anddirection. (e) 1,1-Dichloroethene has a zero dipole moment. (f) The carbon bearing the hydroxyl group in isopropyl alcoholis a 3o carbon. (g) The melting point of a substance is the temperature atwhich equilibrium exists between the well-ordered crystalline state and the more random gaseousstate. (h) Dipole-dipole forces are stronger than ion-ionforces. (i) A hydrogen bond is formed by hydrogen acting a bridgebetween two highly electronegative elements.

Explanation / Answer

   a) False (F) . Since it has only one equilibriumcontitutional form i,e.. salicylate ion.    b) True (T)    c) True (T)    d ) True (T) e ) False(F) since there are an unequivalentgroups are attached to the two different carbon atoms . f) False (F) : Here the carbon bearing thehydroxyl group in isopropyl alcohol is 20 carbon.    g ) False( F) : It is the equilibrium stateof Solid to liquid. h ) false(F) : Since dipole -dipole intractionforces are weaker than ion-ion intraction forces . This is due topartial charges                        are developed in dipole -dipole type but ion-ion type pure ioniccharges are present hence they are more                        stronger forces. i ) False (F) : Hydrogen bond fromed between one atomwith high elctronegative and small size and the another atom hasnon metal with small size.
