The lone pair - OH bond repulsion in water is greater than the OH bond- OH bond repulsion. In methane all of the bonds are the same so it has perfect tetrahedral symmetry. This is VSEPR theory

The CH4 Bond Angle Will Be 109.5 Degrees Because It Has a Tetrahedral Molecular Geometry.
there are 2 pi bonds and 1 sigma bond in propyne (alkynes)
The chemical formula of propyne is CH3C≡CH.
Propylene and propene are synonyms for the same compound with the chemical formula C3H6.If you meant "which is more reactive: propene or propyne", the former being the alkene (contains a double bond) and the latter being the alkyne (contains a triple bond), then propyne should be the more reactive.This is, perhaps, due to the relatively higher steric accessibility of the 4 π(pi)-electrons in propyne (uncited).
The 3 in front of the propyne means that the triple bond is between the 3rd and 4th carbon of the longest carbon chain in the molecule. However, you only have 3 carbons in a chain.
Propyne is not called 1-propyne because the prefix "1-" is used to indicate the location of a functional group on a carbon chain when there are multiple sites of attachment. In the case of propyne, there is only one carbon in the chain, so no numbering is needed.

Bond angle is 109.5 degrees.It is equal in every bond
NH4+ is tetrahedral, with bond angle of 109.5o
the f-p-f bond angle is 120the cl -p-cl bond angle is 180and the f - p - cl bond angle is 90
Three carbon atoms can be arranged in a triangle (cyclopropane), an approximately 109 degree angle (propane), a 120 degree angle (propene), or linearly (propyne).
