Question

(k)Trifluoroacetic acid has a smaller pKa than aceticacid.

(l) Ahydrogen attached to an sp3 carbon ismore acidic than a hydrogen attached to an

sp2 carbon.

(m) Achloro substituent attached to carbon exhibits an electron donatinginductive

effect.

(n)Exothermic reactions usually have a positive (+) enthalpy ofreaction.

(o) Anegative value of Go isassociated with reactions that favor the formationof

productswhen equilibrium is reached.

(p) Apositive entropy change makes a negative contribution to the changein free

energy andis energetically favorable for the formation ofproducts.

(q) Aprotic solvent is one that has a hydrogen atom attached to astrongly

electropositive element such as oxygenand nitrogen.

(r) Acetateion is destabilized by the delocalization of the negativecharge.

(s)The tert-butyl cationis an intermediate in the formation of tert-butylchloride from

thereaction of tert-butylalcohol with concentrated HCl.

(l) A hydrogen attachedto an sp3 carbon is more acidic than a hydrogen attached toan

sp2 carbon. not true sp carbon is more acidicthan sp2.

(m) A chloro substituentattached to carbon exhibits an electron donatinginductive

effect. falsedonating needs to be withdrawing

(n) Exothermic reactionsusually have a positive (+) enthalpy of reaction. False(-)

(o) A negative value ofGo isassociated with reactions that favor the formation of

products whenequilibrium is reached. T

(p) A positive entropychange makes a negative contribution to the change infree

energy and isenergetically favorable for the formation of products. T

(q) A protic solvent isone that has a hydrogen atom attached to a strongly

electropositive elementsuch as oxygen and nitrogen. F (electronegative)

(r) Acetate ion isdestabilized by the delocalization of the negative charge. F(Acetate is stabalized by resonance)

(s) Thetert-butyl cation is an intermediate in the formationof tert-butyl chloride from
