Key terms: Reset anions are strong nucleophiles that open epoxide rings by an SN2 mechanism. tautomers have an O-H group bonded to a C=C. are formed from terminal alkynes with the addition of water using BH3 then H2O2. are constitutional isomers that differ in the location of a double bond and a hydrogen and exist in an equilibrium with each other. are compounds that contain a carbon-carbon triple bond. of a terminal alkyne adds BH₂ to the less substituted, terminal carbon. tautomers have a C=O and an additional C-H bond.

Explanation:

Reset Acetylide  anions are strong nucleophiles that open epoxide rings by an SN2 mechanism. Enol tautomers have an O-H group bonded to a C=C. aldehydes are formed from terminal alkynes with the addition of water using BH3 then H2O2. tautomers are constitutional isomers that differ in the location of a double bond and a hydrogen and exist in an equilibrium with each other. alkynes are compounds that contain a carbon-carbon triple bond. Hydroboration of a terminal alkyne adds BH₂ to the less substituted, terminal carbon. Keto tautomers have a C=O and an additional C-H bond.

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
