This ideal situation already falls apart in the second period where the bond angles of ammonia and water are unusually large; this is because the central atoms are too small to accomodate two or three bonding partners at $90^\circ$ angles so the bond angles are increased in a delicate balance until the lowest overall energy is obtained. Functional Groups: Ascorbic acid has 4 #9 - Bond Angles (Chemistry) > Chemical Bonding and Molecular Structure. 11 (PubChem release 2019. For these two elongated bond Hydrogen adjust the H-Si-H bond angle to 15 degrees.
