Question

The following two figures represent.

• A. (i) $\mathrm { BeCl } _ { 2 }$ is a dimer in vapour phase; (ii) $\mathrm { BeCl } _ { 2 }$ is chain structure in solid state.
• B. (i) $\mathrm { BeCl } _ { 2 }$ is in solid state; (ii) $\mathrm { BeCl } _ { 2 }$ is in vapour phase
• C. (i) $\mathrm { BeCl } _ { 2 }$ is monomer in solid state; (ii) $\mathrm { BeCl } _ { 2 }$ is linear polymer in vapour phase.
• D. (i) $\mathrm { BeCl } _ { 2 }$ is linear monomer; (ii) $\mathrm { BeCl } _ { 2 }$ is three dimensional dimer.

Answer 1

Answer: (A)

(i) $\mathrm { BeCl } _ { 2 }$ is a dimer in vapour phase; (ii) $\mathrm { BeCl } _ { 2 }$ is chain structure in solid state.

Answer 2

: (i) Is a dimer of $\mathrm { BeCl } _ { 2 }$ in vapour phase.

(ii) is a chain structure os $\mathrm { BeCl } _ { 2 }$ in solid phase.
