1 answer:
Answer:
HOMO of 1,3-butadiene and LUMO of ethylene
HOMO of ethylene LUMO of 1,3-butadiene
Explanation:
1,3 - butadiene underogoes cycloaddition reaction with ethylene to give cyclohexene.
According to Frontier molecular orbital theory HOMO of 1,3 butadiene and LUMO of ethylene and HOMO of ethylene and LUMO of ethylene underoges (4 + 2) in thermal or photochemical condition.

Answer:
6.02 x 10²³ electrons
Explanation:
Given parameters:
Mass of H₂ = 2g
Unknown:
Number of electrons = ?
Solution:
To find the number of electrons, we must determine the number of moles of H₂ first.
Number of moles =
Molar mass of H₂ = 2(1) = 2g/mol
Number of moles = = 1mol
1 mole of a substance contains 6.02 x 10²³ particles
the particles can be protons, neutrons, electrons
So,
2g of H₂ will contain 6.02 x 10²³ electrons.
