question 6 (0.5 points)
give the best systematic name for the compound
sebr6 1 2
a. selenium b. selenium (vi) c. monoselenium d. bromine
e. bromide f. hexabromine g. hexabromide h. sia

Explanation:

In naming binary molecular compounds, the first - named element is the less electronegative one (selenium, Se) and the second is the more electronegative (bromine, Br). The prefix for one atom of the first element is usually omitted. The prefix for six atoms of the second element is 'hexa -'. The second element has its ending changed to '-ide'. So for $SeBr_6$, the first part of the name is 'selenium' and the second part is 'hexabromide'.

Answer:

A. selenium
G. hexabromide
