Homework Answers
1) least stable alkene (highest in energy) is: C
most stable alkene (lowest in energy) is: A
Explanation: more substituted alkene is most stable and less substituted alkene is least stable. so tri substituted alkene is more stable and mono substituted alkene is least stable.
2) least stable alkene (highest in energy) is: B
most stable alkene (lowest in energy) is: C
Explanation: Tetra substituted alkene is most stable and mono substituted alkene is least stable.

For the gas phase isomerization of isopropenyl allyl ether, CH2=C(CH3)-O-CH2CH=CH2– CH3COCH2CH2CH=CH2 the rate constant has been determined at several temperatures. When In k in sis plotted against the reciprocal of the Kelvin temperature, the resulting linear plot has a slope of -1.48x104 K and a y-intercept of 26.0. The activation energy for the gas phase isomerization of isopropenyl allyl ether is kJ/mol.

H3 C H2Br Br2, H30* HC X CH3 HzC CH3 H3C CH3 Aldehydes and ketones can be halogenated at their a-position by reaction with Cl, Br, or 12, under acidic conditions. Using Br2 under acidic conditions, an intermediate enol is formed which adds bromine at the a-position. The reaction stops after the addition of one bromine because the electron-withdrawing halogen decreases the basicity of the carbonyl oxygen, making the protonation less favorable. Not started curved arrows to show the movement...
