Draw the Lewis structure for each organic compound from its condensed structural formula. b. CH3OCH3
검증된 단계별 안내1
Identify the atoms in the condensed structural formula CH3OCH3. There are two carbon (C) atoms, one oxygen (O) atom, and six hydrogen (H) atoms.
Determine the connectivity of the atoms. The formula suggests that the oxygen atom is between the two carbon atoms, forming a C-O-C linkage.
Draw the carbon atoms first, and connect them with a single bond to the oxygen atom: C-O-C.
Attach the hydrogen atoms to the carbon atoms. Each carbon atom in CH3 has three hydrogen atoms attached, so add three hydrogens to each carbon.
Ensure that each atom satisfies the octet rule (or duet for hydrogen). Carbon should have four bonds, oxygen should have two bonds, and hydrogen should have one bond.

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.
Lewis Structures
Lewis structures are diagrams that represent the bonding between atoms in a molecule and the lone pairs of electrons that may exist. They use dots to represent electrons and lines to represent bonds between atoms. Understanding how to draw Lewis structures is essential for visualizing molecular geometry and predicting reactivity.

Condensed Structural Formula
A condensed structural formula provides a shorthand way of representing the structure of a molecule, showing how atoms are connected without depicting all the bonds explicitly. For example, in CH3OCH3, the formula indicates that there are two methyl groups (CH3) connected by an oxygen atom, which is crucial for understanding the molecular structure before drawing the Lewis structure.

Valence Electrons
Valence electrons are the outermost electrons of an atom and are involved in forming bonds with other atoms. Knowing the number of valence electrons for each atom in a molecule is vital for accurately drawing Lewis structures, as it determines how atoms will bond and the overall stability of the molecule.

교과서 질문
The cyanate ion (OCN- ) and the fulminate ion (CNO- ) share the same three atoms but have vastly different properties. The cyanate ion is stable, while the fulminate ion is unstable and forms explosive compounds. The resonance structures of the cyanate ion are explored in Example 10.8. Draw Lewis structures for the fulminate ion—including possible resonance forms— and use formal charge to explain why the fulminate ion is less stable (and therefore more reactive) than the cyanate ion.
