An alkene reacts with a strong protic acid to form a carbocation. However, an alkene will react with a halogen electrophile to f
orm a cyclic intermediate. Draw the curved arrow notation for both reactions.
1 answer:
Answer:
Reaction mechanisms are shown below.
Explanation:
Alkene gives nucleophilic addition reaction with strong protic acid.
Proton from a strong protic acid ruptures pi-bond in alkene and makes a new C-H sigma bond and thereby produces a carbocation.
Lone pair on halogen atom first adds onto double bond by rupturing the pi-bond and this pi-bond electrons then simultaneously substitutes a halogen atom from diatomic molecule of halogen to produce a cyclic halogenium cation by forming two new C-X sigma bonds. (X=halogen atom)
Reaction mechanism has been shown below.

A sample of aluminum, which has a specific heat capacity of 0.897 JB loc ! is put into a calorimeter (see sketch at right) that contains 200.0 g of water. The aluminum sample starts off at 85.6 °C and the temperature of the water starts off at 16.0 °C. When the temperature of the water stops changing it's 20.1 °C. The pressure remains constant at 1 atm. Calculate the mass of the aluminum sample.
Answer:
Explanation:
From the question we are told that:
Heat Capacity
Mass of water
Initial Temperature of Aluminium
Initial Temperature of Water
Final Temperature of Water
Generally
Heat loss=Heat Gain
Therefore
