S(CH3)2 is the formula for Dimethyl Sulfide analogous to Dimethyl ether
Fcr=pi^2*E*I/((KL)^2
The equation for force (F) is mass (m) multiplied by acceleration (a). In SI units force is measured in Newtons (N), while 'm' is in kilograms and 'a' is in meters per second per second (m/s^2).
Where n = number of nodes The number of connections in a full mesh = n(n - 1) / 2
C = 2*B*log2(M) where C --> capacity B --> bandwidth M --> # of discrete signals
Where n = number of nodes The number of connections in a full mesh = n(n - 1) / 2
A semi-structural formula for this molecule is CH3-(CH2)2-CH=C(CH3)-CH3.
CH3-C(Br)(CH3)-CH3 + H2O = CH3-C(OH)(CH3)-CH3 + HBr
Formula: [S(CH3)3]I
2,2,3- trimethyl pentane has the structural shape. CH3-C(CH3)2-CH(CH3)-CH2-CH3 C8H18 is the condensed /reduced formula.
CH3-CH=CH2-CH2-CH2-CH3 CH3
The formula is: (CH3)2C(C6H4OH)2
Ch3ch(ch3)c(ch3)2ch(ch3)(ch2)4ch3
Ch3ch2ch(ch3)ch2ch=o
This is already a structural formula CH3-CH=CH-CHO of 2- butenal or Butanal-2-en
C2H8N2 is molecular formula so empirical formula is C1H4N1
Ethanol is C2H5OH and dimethyl ether is CH3-O-CH3. Both are C2H6O.
Acetone (2-propanone, propanone, or other names) has CH3COCH3 as its chemical formula. But it shares that formula with propionaldehyde (propanal). The two chemicals are structural isomers, and they have clearly different chemical properties. That's why we have a scheme for the structural formula of an organic compound. Since we can't "draw" here, use the link to a nice picture of the structural formula of acetone. The information is provided by our friends at Wikipedia, where knowledge is free.
