Hi everyone,
Today i will be sharing with you one question that i have included in the GCE O-Level Pure Chemistry Topical Ten Years Series (2002 – 2011) book (by FBP publisher) that i have authored 2 years ago.
The question is related to the topic Chemical Bonding and i have included into the book as an additional question for students to build on their fundamental concepts.
Question:
Elements X and Y are elements found in the second period of the Periodic Table.
Element X combines with carbon to form a covalent compound with structural formula of X=C=X.
Element Y reacts with sodium metal to form an ionic compound with chemical formula NaY.
What is the most likely structural formula for the covalent compound X2Y2?
A) X-Y-Y-X
B) X=Y-Y=X
C) Y-X-X-Y
