which has covalent bonds?\na glucose\nb table salt\nc steel alloy\nd iron oxide - rust
Answer
Brief Explanations:
Covalent bonds occur when atoms share electrons. Glucose ($C_6H_{12}O_6$) is a molecular compound with covalent bonds between its carbon, hydrogen, and oxygen atoms. Table salt (sodium chloride, NaCl) has ionic bonds. Steel alloy is a mixture of iron and other elements with metallic - bonding characteristics. Iron oxide (rust) has ionic bonds due to the transfer of electrons between iron and oxygen.
Answer:
A. glucose
