Which substance in the reaction serves as the electrophile?'?
jok3333 [9.3K]

Electrophiles are reagents attracted to electrons.

Electrophiles tend to be electron-deficient and carry partial positive charges. They are attracted to species with lone pairs of electrons. For example, protons \text{H}^+ have no electrons and tend to share ones with other species, hence behaving as electrophiles in aqueous reactions. In the reaction between \text{H}^+ and ammonia \text{NH}_3, protons would be attracted to lone electron pairs on nitrogen atoms in ammonia molecules, which carry partial positive charges.

The Lewis Acid-base theory define Acids as species that accept electron pairs in a particular acid-base reaction. Electrophiles, by definition, tend to accept electrons. Lewis acids thus behaves as electrophiles in acid-base reactions. In the previous example, \text{H}^+ demonstrates acidic behavior and can be inferred as an electrophile.

Suppose you had 2.0158 grams of (H2) how many moles of hydrogen do u have ?
ale4655 [162]
\hbox { You have to calculate the Molecular Mass for H2:}

M_{H2} = 2A _{H2} = 2*1=2 \hbox { grames/mole}

\hbox { So, in 2,0158 grames of H you will have 1 mole...}

How do you convert ethane to ethanoic acid? (with equation please).
Bess [88]
Ethane can be turned into its carboxylic acid form called the ethanoic acid by a series of steps. First chlirinate it in the presence of light. Then, add potassium hydroxide to get an alcohol. Finally, adding KMnO4 to oxidize it to a carboxylic acid. The equations are as follows:
C2H6 + Cl2  ---> C2H5Cl + HCl
C2H5Cl+KOH-> C2H5OH+ KCl.
C2H5OH  ----KMnO4 ---> CH3COOH.

The best way seperate salt fron wateris with the use of
ExtremeBDS [4]

You can boil or evaporate the water and the salt will be left behind as a solid. If you want to collect the water, you can use distillation. This works because salt has a much higher boiling point than water. One way to separate salt and water at home is to boil the salt water in a pot with a lid. So, I would say maybe oil.
