1.	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
Answer» Equal to CI - Be - C angle in `[Be(CI_(2))]_(n)` Less than CI - Be - C angle in `[Be(CI_(2))]_(n)` Greater than the CI - Be - C angle in `[Be(CI_(2))]_(n)` NO REACTION to CI - Be - C angle in `[Be(CI_(2))]_(n)` Solution :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
