Alkoxides of beryllium [Be(OR)(2)](6) us...

Alkoxides of beryllium `[Be(OR)_(2)]_(6)` usually have associated strutures with both `mu_(2)` - bridging and terminal OR groups. For example `[Be(OCH_(3))_(2)]_(6)` is a high polymer insoluble in hydrocarbon solvents. On the other hand, tertiary - butoxy derivative is less condensed being only a trimer `[Be(O-t-Bu)_(2)]_(3)`
The C - Be - C angle `[Be(CH_(3))_(2)]_(n)` is

A

Equal to CI - Be - C angle in `[Be(CI_(2))]_(n)`

B

Less than CI - Be - C angle in `[Be(CI_(2))]_(n)`

C

Greater than the CI - Be - C angle in `[Be(CI_(2))]_(n)`

D

NO reaction to CI - Be - C angle in `[Be(CI_(2))]_(n)`

Text Solution

Verified by Experts

The correct Answer is:
B
The C - Be - C angle in `[Be (CH_(3))_(2)]_(n)` is less than CI - Be - C angle in `[Be (CI_(2))]_(n)` due to electronegative difference
