Question

lel 4: Electrophiles Il that an electrophile (E) is a Lewis Acid which accepts electrons. HO C H,Br (ChalCH CH3NH2 stions: For the compounds listed in Model 4: (a) Circle the compounds that could act as electrophiles, cross out those that would not (b) Explain why the compounds circled could act as electrophiles. (c) What feature must all electrophiles have? (d) Once your group has reached consensus, come up with an explanation of why the crossed out compounds would not act as electrophiles. Consider the following reaction: R- X R + x (a) (b) Label the RX bond with 8+ and 8- to indicate bond polarity. Why would RX be considered to be an electrophile? Consider the acid dissociation of HX below: H-X H@ + x (a) if Xe is stable, is HX likely to accept an electron pair, to form products? Explain. (b) if Xe is a strong base, is HX likely to accept an electron pair, to form products? Explain. (c) if Xe is a weak base, is HX likely to accept and electron pair, to form products? Explain.
I need help being walked through each part please

Answer 1

The detail answers on the model 4 -electrophiles and the strength of the acid by their dissociation into the nature of the conjugated base were explained as below. All the sub parts of the three questions have been discussed as below.

PAGE NO: DATE: a. Hoo (Alz Ber) Mach May The cirded compound / species are electophile b. Elecbophites are positively charged of neutral speeres having vacant orbital which can be atracted to an electron nich Centre - f.e by nudeophile c) All, electrophiles kare vacant odbitals. Electophiles are an eleeben, pair accepers. Albo inaen as electron delicient species. d) The Crossed groups are having negative charge and they act as nucleophiles? These species have rich in electons therefore they donate the electons to Gleetin dextraient species. Conside the tollreeing reaction a) Partial charges explain the bond polarity 6. Rx is considered as electrophite as the X is vely changed species & act as leaving Gorup. This the R Carries positive charge

The R is in search of electrons to form the bend. Any nucleophile IGNU) can attack to R-X and the new bond is formed as Nu-R Therefore x act as electrophile Consider the aid dissociation I HX - HO + x a) y fis stable by eleconace with dracking group then the aerd 14-x world be soring acro, Means He will accept eleetons pair. b). The x is conjugate base of acid (4-7). If the x is strong conjugale base, the acid (A ) world be weak geld and will not accept the election pair to term bend easty, To if the is weak base, then the aero CH-X) is stronger & hence it will accept electoon pour & will torm the bond with elepon rich species.
