What is the molecular geometry, or shape, of beryllium chloride (becl2)? a. tetrahedral b. linear c. trigonal pyramid d. bent

linear

Explanation:

The shape of BCl₂ is linear. The central Be atom has 2 valance electron and so Be has coordination number of 2. In the Be-Cl covalent bond a pair of electron is shared by the Be and the Cl atoms. The bond angle in BeCl₂ is 180°. To account for the bond angle it has been proposed that Be has sp hybridization and each of the two sp hybrid orbital of Be overlaps with the p orbitals of Cl.

B. linear

Explanation:

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

increased stability in the completion of fluorine's outer shell.
