Who is lightest Hydrogen molecule or methane molecule?
Hydrogen molecule is the lightest because of its atomic mass being less than any other molecule .i.e 1amu (atomic mass unit). Hence Hydrogen molecule is lighter than Methane molecule.
Is CSH2 polar or nonpolar?
It is polar, S has 2 lone pairs of electrons which repel the hydrogens. In turn, the hydrogens are pressed towards each other, resulting in a positive charged part of the molecule and the S the negative.Hence, we have a polar molecule.
Does methane float on water?
No. methane is not soluble in water, as methane is a non-polar hydrocarbon and water is a polar solvent.
Is methane a compound consisting of molecules held together by weak intermolecular forces?
Given that methane is a gas at room temperature, we can see that its molecules are attracted to each other only by weak intermolecular forces. But normally, if I say "methane is a compound consisting of..." the statement concludes, one carbon atom and four hydrogen atoms. That's what the methane molecule consists of.
Is AlH4- polar or non polar?
GeH4 is tetrahedral- (same as methane) - any polarity in the Ge-H bonds cancels each other out - do the molecule is non-polar.
What makes chemically unique primary hydrogens different from other types of hydrogen atoms in a molecule?
Chemically unique primary hydrogens are different from other types of hydrogen atoms in a molecule because they are directly attached to a carbon atom that is only bonded to one other carbon atom. This makes them more reactive and susceptible to chemical reactions compared to other hydrogen atoms in the molecule.
Water is considered a polar molecule?
Yes, Hydrogens on one side and the electronegative oxygen at the other.
Who is lightest Hydrogen molecule or methane molecule?

Why does methane not dissolve well in water?
Methane is nonpolar while water is polar, which means they have different intermolecular forces. Water molecules prefer to interact with each other through hydrogen bonding, making it difficult for methane molecules to become fully solvated in water. This difference in polarity and intermolecular forces leads to poor solubility of methane in water.
Molecule that consists of one carbon and four hydrogen atoms?
The molecular formula is CH4. This molecule is know as Carbon tetrahydride or more simply Methane.
Is CSH2 polar or nonpolar?
It is polar, S has 2 lone pairs of electrons which repel the hydrogens. In turn, the hydrogens are pressed towards each other, resulting in a positive charged part of the molecule and the S the negative.Hence, we have a polar molecule.
What substance has a stronger force of attraction between its particles water or methane?
water has very high intermolecular forces called hydrogen bonding, methane is nearly unaffected by it's neighbor methanes. oxgyen has a high electronegativity value, making the water molecule mostly negative near the oxgyen and positive near the hydrogen atoms. this causes a polar molecule, which are attracted to nearby molecules of water. that's why water has such a high boiling point for being such a small mass molecule. methane has carbon central, four hydrogen's at the "corners". carbon's electronegativity is about 2.6 to hydrogen's 2.1. net the carbon gains these electrons mostly in the covalent bonds, but all four hydrogens become a sort of "positive" zone since they "lose" their bonding electron most of the time to carbon. since all the outer atoms (the hydrogens) for all of the local methane molecules are the same, all this positive charge repels from each other, making for much lower boiling points, little intermolecular attraction. linus pauling won the noble prize in chemistry for his work in this bonding phenomenon.
Which molecule is more likely to exist in nature a molecule of CH3 or a molecule of CH4 Explain?
A molecule of CH4 (methane) is more likely to exist in nature because it is a stable compound with all valence electrons satisfied through covalent bonding. A molecule of CH3, on the other hand, would be highly reactive due to the presence of an unpaired electron on the carbon atom, making it less likely to exist in nature.

Does methane float on water?
No. methane is not soluble in water, as methane is a non-polar hydrocarbon and water is a polar solvent.
Why is the pka of fluorenone different that other ketones?
9-fluorenone is different because it is a ketone with all of its carbons tied up in double bonds. There are no readily available acidic hydrogens, therefore this makes the pka of the molecule much greater than most other ketones.
What is the pKa of an allylic hydrogen and how does it compare to other types of hydrogens in organic molecules?
The pKa of an allylic hydrogen is typically around 44-45, which is higher than other types of hydrogens in organic molecules. This means that allylic hydrogens are less acidic compared to other hydrogens, such as those in alcohols or carboxylic acids.
