Question

A hydrocarbon is a compound made up of C and H atoms only. Consider the following incompletely drawn hydrocarbon molecule:
C-C=C-C-C
The formal charge on all the atoms is zero. To complete the structure, the number of H atoms that must be bonded to the second C is

Answer 1

Question #61601 - Chemistry - General Chemistry

From the IUPAC perspective, the numeration will be following:

$$C ^ {1} - C ^ {2} = C ^ {3} - C ^ {4} - C ^ {5}$$

Though, completely drawn molecule has a structure (below), the answer is 1(one).

(or) $\mathrm{H}_3\mathrm{C - CH = CH - CH_2 - CH_3}$

The calculation was operated counting that a Carbon has a valence number 4 when zero electric charges.
