Answer

The semi-structural formula for V is CH₃CHClCH₂CH₃, as derived from the reaction with Cl₂.

Step 2

ii. W

104 rated

Answer

W can be identified with the semi-structural formula CH₃CH₂CH₂CH₃, as it is the butane molecule that reacts to form V.

Step 3

iii. X

96%

101 rated

Answer

X has the same molecular formula as V, which is C₄H₉Cl. A possible semi-structural formula for X is CH₂ClCH₂CH₂CH₃.

Step 4

iv. Y

98%

120 rated

Answer

Y is indicated in the reaction with water, and its semi-structural formula is CH₃CH₂CH₂OH.

Step 5

v. Z

97%

117 rated

Answer

The semi-structural formula for Z is CH₃, resulting from the splitting of butane.
