Question

Let’s Recall
A. Write the integer that is represented by each point.
E A C D B

1. A 4. D
2. B 5. E
3. C

Answer 1

Theorem: Let aa, bb, and cc be integers with a$\large{\cancel{=}}$0 and b $\large{\cancel{=}}$0.

If a | ba | b and b | cb | c, then a | ca | c.

Answer 2

IUPAC Name = (2Z 5Z) 3-bromo hepta-2,5-diene

Priority = Double bonds

Functional group = Halogen

Substituent = Bromine

Longest C-chain = 7

Molecular formula = C7H11Br

Molecular mass = 174.9 g/mol

Calculation -

→ 12×7 + 1×11 + 79.9

→ 84 + 11 + 79.9

→ 174.9

Isomerism = Geometrical isomerism

Type = E and Z isomer

Note -

E = If substituent is attached opposite side to each other in double bonded C-atom.

Z = If substituent is attached same side in double bonded C-atom.
