What is the systematic name for PH3?
It contains a lone pair of electrons. Hence, it can donate it thereby ,its a base. The tendency to donate the electron pairs can determine the basicity of a base. Therefore, PF3 is less basic than PH3.
Why is the bond angle in PH4 higher than PH3?
The bond angle in PH4 is higher than PH3 because PH4 has a tetrahedral molecular geometry with bond angles of about 109.5 degrees, while PH3 has a trigonal pyramidal molecular geometry with bond angles of about 107 degrees. This difference in bond angles is due to the presence of an additional hydrogen atom in PH4 compared to PH3.
How many atoms does the formula PH3 have?
The formula PH3 represents one phosphorus atom and three hydrogen atoms. Therefore, PH3 has a total of four atoms.
Is PH3 symmetric?
No, PH3 is not symmetric. The molecule has a pyramidal shape due to the lone pair on the central phosphorus atom. This asymmetry contributes to the overall molecular geometry of PH3.
Why pure NH3 does not burn in air but impure PH3 burn in air?
With traces of P2H4 present, PH3 is spontaneously flammable in air
Is PH3 is stronger than NH3?
PH3 (phosphine) is considered to be a weaker base compared to NH3 (ammonia) because the electronegativity of phosphorus is greater than nitrogen, making the lone pair on phosphorus less available for donation. This results in NH3 being a stronger base than PH3.
Is pH 4 stronger than pH3?
No, a lower pH value indicates a stronger acid. Therefore, pH 3 is stronger than pH 4.
Which acids would be stronger pH3 or pH5?
The lower the pH value, the stronger the acid. Therefore, pH 3 is stronger than pH 5. pH 3 has a higher concentration of hydrogen ions, making it a more acidic solution than pH 5.
Why does PH3 have a higher vapor pressure then NH3?
PH3 has a higher vapor pressure than NH3 due to the larger size and greater molecular weight of phosphorus compared to nitrogen. This results in weaker van der Waals forces between PH3 molecules, allowing them to escape and become a gas more easily than NH3 molecules.
Is PH3 a ionic or covalent bond?
Neither. It is hydrogeneous.

Ph3 acid or not?
PH3 is an acid.It is a flammable substance.
Why is bond angle in ph3 less than that in nh3?
Both PH3 and NH3 have 3 bonding pairs and 1 lone pair of electrons around the central atom, and so are both trigonal pyramidal in shape. The bond angle in NH3 is less than 109.5º and that in PH3 is less than that in NH3 (maybe around 109º). The reason for this has to due with electronegativity. The N atom is more electronegative than the P atom and thus electron density of N's bonding electrons are closer to the N, and so they exert a greater repulsion on each other. This greater repulsion compared to that seen PH3 makes the bond angle slighter greater in NH3. P being less electronegative than N doesn't draw it's electrons as close so they don't repel as much.
What is the oxidation number of PH3?
The oxidation number of phosphorus in PH3 is -3.
Is PH3 a molecular or ionic compound?
PH3 is a molecular compound. It is made up of covalent bonds between phosphorus and hydrogen atoms, rather than ionic bonds between a metal and a nonmetal.
Which boiling point is higher PH3 or AsH3?
The boiling point of AsH3 (Arsine) is higher than that of PH3 (Phosphine) due to the higher molecular weight of AsH3 compared to PH3. Stronger Van der Waals forces of attraction between molecules in AsH3 result in higher boiling point.
