1) State which of the electrophiles given below will react preferentially by i) SN1, ii) by SN2, or iii) capable of reacting by either of the two mechanisms depending on the given conditions. How can you affect those conditions to favour SN1 or SN2? Reason your predictions based on the structures of the compounds. Br-CH3, Br-CH2CH3, Br-CH(CH3)2, Br-C(CH3)3, Br-CH2-C5H6; C5H6 = phenyl Introduction Alkyl halides can be prepared from alcohols by reactions with hydrogen halides (HCI, HBr, or HI) via...
Which of the following best describes London dispersion forces. Question 1 options: the intermolecular forces that exist when ions from an ionic compound are attracted to the dipole of polar molecules in a mixture. involves molecular orientations in which the positive end of one dipole is near the negative end of another forces that exist only between molecules that contain hydrogen atoms bonded to highly electronegative atoms such as O, N, F. Interactions between temporary dipoles cause atoms to be...
please answer questions 9-12 Question 9 1 pts Which of the following statements describes the reactivity of alkynes? An alkyne is an electron-rich molecule and therefore reacts as a nucleophile. When a symmetrical internal alkyne reacts with HBr, two products are formed. Unlike alkenes, alkynes fail to undergo electrophilic addition reactions The o bonds of alkynes are greater in energy than the rt bonds and, therefore, are more reactive Alkynes react as electrophiles, whereas alkenes react as nucleophiles What is...
