Answer:
Alkenes are <u>Very Reactive</u>.
Explanation:
Other options are incorrect because;
Saturated compounds are those hydrocarbons which contains only single bonds, while alkenes contain atleast one double bond.
Single bonds again stands for saturated compounds, hence it is false.
Alkene are reactive because the double bond has the potential to open by addition reaction. So electrophiles are readily added across double bond. This reactivity can also be explained by the exposure of nucleophilic double bond above and below the plane, which is highly exposed to incoming electrophiles.
Answer:
C6H6
Explanation:
C : 60.0 g*1 mol/12 .01g = 5.00 mol
H: 5.05 g * 1 mol/1.01 g= 5.10 mol
C:H = 5.00 mol : 5.10 mol = 1:1
CH is an empirical formula
Molar mass (12.01 +1.01)=13.02 g/mol
78.12g/mol /13.02 g/mol =6
Molecular formula is the empirical that was taken 6 times (CH)6 = C6H6
Answer:
There are 110 elements known to us, out of which 92 are naturally occurring, while the rest have been prepared artificially. Elements are further classified into metals, non-metals, and metalloids..

We will use the PH formula:
PH = Pka + ㏒ [salt/acid]
PH= Pka +㏒ [lactate/lactic]
when Pka = -㏒Ka
= -㏒ 1.37x10^-4
= 3.86
and we have PH =4.12
So by substitution:
4.12 = 3.86 + ㏒[actate/lactic]
∴[actate/lactic] = 1.82
∴[lactic/actate] = 1 / 1.82
= 0.55
C-Cl bond is polar.
As Cl is more electronegative than C,
Cl pulls the shared electrons towards its side making the C-Cl bond polar.
Polar meaning C gets a partial positive charge and Cl gets a partial negative charge. Thus C-Cl bond becomes polar.
CCl4 molecule is tetrahedral.
And its shape is symmetrical.
That means its similar on all corners or all planes and it can be cut into equal halves from any plane.
C-Cl bond is polar.But the C-Cl polairty gets cancelled out as its pulled equally from all sides.
Since the molecule is symmetrical CCl4 is non polar.
