A student wanted to prepare an alkane by adding a proton to a carbocation. Basing on your knowledge of carbocations, would the student have been successful? Explain your reasoning.
Homework Answers
Carbocarions are sp2 hybridized carbons, because of thier the empty p orbitals they are electron deficient. Thus, the carbocation will not accept protons as protons are as well electron deficient. Carbocation and proton will not react, so the student wouldn't able to make alkane by reacting carbocation and proton.
Insted, if student react cabocation aith hydride (H-, proton with two electrons) then it is possible to make alkane from carbocation.

Discuss the effect of each of these “experimental errors” on the calculated Cs, metal. EXPLAIN your reasoning. a. A student measures the mass of the water+calorimeter before adding the metal, and right as the metal is dropped in, some water splashes out. b. A student takes the metal out of the hot water bath, c/and allows it to cool a little before placing it into the DI water in the calorimeter.
