CBSE Class 10 Science 2020 · Paper 31/5/1 · Question 1
Covalent compounds are generally poor conductors of electricity. Why ?
Answer
Covalent compounds have no ions or free electrons to carry charge, so they are poor conductors.
Because covalent compounds contain no charged particles (ions) to carry the current. Their atoms are bonded by sharing electrons, so no ions are formed and the compound is made of neutral molecules; with no ions (and no free electrons) to move and carry charge, covalent compounds are generally poor conductors of electricity.
