Question

question 8 (0.5 points) give the best systematic name for the compound w4c5 1 2 a. tungsten b. tetratungsten c. tungsten (v) d. carbon e. carbide f. pentacarbide g. tetracarbide h. willy

Explanation:

In naming binary compounds, the element with the lower electronegativity is named first. Here, tungsten (W) is named first. The prefix for 4 is "tetra -", so it's tetratungsten. Carbon forms the carbide ion, and with 5 carbon atoms, the prefix for 5 is "penta -", so it's pentacarbide.

Answer:

1. B. tetratungsten
2. F. pentacarbide
