Determine the correct order of bond angles around the oxygen atom in methoxymethane (Me-O-Me), disilyl ether (H3Si-O-SiH3), and bis(triphenylsilyl) ether ((Ph)3Si-O-Si(Ph)3)
Choose the correct bond angle sequence from largest to smallest:
1
(Ph)3Si-O-Si(Ph)3 > H3Si-O-SiH3 > Me-O-Me
2
Me-O-Me > H3Si-O-SiH3 > (Ph)3Si-O-Si(Ph)3
3
H3Si-O-SiH3 > Me-O-Me > (Ph)3Si-O-Si(Ph)3
4
(Ph)3Si-O-Si(Ph)3> Me-O-Me > H3Si-O-SiH3
